" Application filed August 1l,

To alti Awhom it 'may concer/nf.'

Be it known thatl, 'JOHN llt. (lnnooiii', a citizen of the United States, residing at Coldwater, in the county of Lincoln and State ot' Tennessee, have invented a new and useful l-nenniatic tiirlieeder, of which the followis a spccii-ation. i

The invention relates to iniproveiiients in pneumatic conveyors for carrying the cotton troni a. wagon to the gin house.

'l'hc objectof the present invention is to improve the construction otpneinnatic coni'oyers for feeding cotton gins, and to provide a simple, inexpensive and etiicient construction, adapted to enable the feed pipes of a pneumatic conveyor to loosen up the cotton in a. wagon to enable the pneuniatic conveyor to operate with great` rapidity without the diiiiculty and inconvenience of :-.a.;ia.tchiiig or raking the cotton loose by hand.'

With these and other objects in view, the

nove' n 'ibination of parts hereinafter `it'ully f, illustrated in the accompanying I and pointed out in the clainisfherefl' id; it being understood that variclnii D s in 'the torni, proportion, size and minor details oit construction, within the scope ot' c claims, niay be resorted to witht sacrificing a departing troni the spirit or olf thc advantagcsof the invention. ln the drawing:---Figure "l ,is an' elevation ot' a portion ot a pneuniati'c'ctuiveyer having feed pipe, constructed in accordance with is invention Fig. is a horizontal secnal view, tal'en substantially on the line Fig. 3 is an end View, showot' l. ing the lower end of the feed pipe. jli`ig. is a vert-ical sectional view, taken vrsubstantiall).I on the line llc-fl of F ig. 2. Fig. 5 is a detail sectional view, illustrating the manner ot securing the. collar to the lower end ot' the feed pipe. y

Like numerals of reference designate corresponding parts in all the tigures ot the drawing.

l designates a vertical telescopic feed pipo, constituting the lower section or ineniber ot' the pneumatic conveyor Q and having a slidable telescopic connection with the pipe or member 3,. fitted within the upper end of the feed pipe, clearly illustrated in Fig. 'l oi' the drawing. The feed pipe is vertically movable to raise and loweijit to suit the amount of cotton 4 within a wagon 5, and

die. section 3 is connected with the adjacent upper portion of the conveyor' by ineans ot a flexible section (3', adapted to permit the feed pipe to be inoved hoifizontallyfin any direction so as to operate on the entire contents of the Wagon 5.

` In order to avoid thediticult and inconvenientoperation of loosening' the. cotton. by

vhand to perinit the saine lto be operated on ,eltectively by the pneumatic conveyor, the ylatter iseqiupped at its lower end with a series of vertical .teeth 7, consisting of' rods, v

yhaving threaded upper portions 8, which The sectional collar Si, which encircles the lower end of the `feed pipe, fis provided with threaded per-4 torations l() for the reception of upper threaded portions 8, lock nutsll being preferably arranged on the upper threaded terininals of the teeth for preventing the saine troni accidentallyy becoming loose. The teeth formed by thev vertical rods 7 are arranged in an arcuate series, and are located outside of the :t'eed pipe and extend below the saine. The teeth are adapted to loosen up the cotton to enable the saine to be rapidly carried away by the pneumatic conveyor.

Y The lower end of the feed pipe is provided with an exterior' annular rib 12, forming an upper horizontal shoulder against which the sectional collar 9 is fitted. The sections of the collar are provided with' laterally e.\;- tending lugs 13, which are pierced by horizontal connecting bolts 14- foi" securing the sections together. The collar is securely held on the shoulder or seatforined by the rib 12 by means of a plurality of hooks 15, extend 'ing around the rib 1Q from the exterior thereof and engaging the lower edge ofthe feed pipe, as clearly shown in Fig. 5 of the drawing. The hooks are, provided with threaded Shanks 16, piercing the collar and secured to the saine by nuts 17. The hooks detachably fasten the collar on the lower end ct' the feed pipe and prevent the collar from slipping when the eon'veyer is in use. The sectional collar is also equipped at opposite sides with 'vertical handles 18, extending up ward troni and carriedby one of the sections of the collar, as clearly shown in Fig. 2 of the drawing. These handles are arran' ed in convenient position to enable the fee pipe to be firmly held and guided by the operator, 'who the use of the conveyormoves the lower end of the feed pipe backward and forward over the cotton to 'cause the teeth mounted in a suitable bracket or anger 22,'

which depends from a horizontal portion of u. conveyor. One end of the flexible connection is secured to the weight 19, and its other end is attached to an eye 23, consisting of a substantially Ushaped fastening sta le, the sides or legs of which piercethe colllar, as clearly shown in Fig: 4.

The horizontal top portion of the conveyer is designed to extend 1n the usual manner'to a gin house (not shown). l

The sectional collar enables the improvement to be readily applied to the feed pipe of an ordinary pneumatic cotton feeder or con` veyer.

Having thus fully described my invention, what 1 claim as new and desire to secure by Letters Patent, is zi. An attachment for pneumatic cotton conveyors including a collar adapted to encircle the feed pipe of a conveyor and provided..` with means for engaging the same, teeth rigid with and depending from the collar and arranged to project beyond the iced pipe, and a handle carried by the collar.

An attachment for pneumatic cotton conveyers including a collar adapted to be arranged on the feed pipe of the conveyer,

hooks adjustably secured to and projecting from the bottom for engaging the lower edge of the feed pipe, and a series of teeth piercing the collar and secured to the same.

3. The combination with the feed pipe, of a conveyer provided at its ends with an ex` terior shoulder, of a collar encircling the feed pipe and seated on the said shoulder, hooks piercing the collar and engaging the lower edge of the feed pipe, and a series of teeth consist-ing of rods extending below the feed pipe and having upper portions piercing the collar.

4. The combination with the feed pipe of a conveyer rovided at its ends with an eX- terior shou der, of a sectional collar encircling the feed pipe and seated on the said shoulder, hooks piercing the collar and engaging the lower edge of the feed pipe, vand i a series of teeth consisting of rods extending below the feed pipe and having upper por tions piercing thel collar, and opposite han; dles extending upward from the collar and carried by one of the sections thereof.

5. The combination of a conveyer having a vertically movable .feed pipe, a collar secured to the lower end of the feed pipe and provided with depending teeth and having an eye, a counter-balancing weight, and a iiexible connection having the weight secured to one end of it and connected at its other end to the eye of the collar. y

In testimony, that I claim the lforegoing GOr as my own, I have hereto affixed my signature in the presence of two witnesses.
